[0002]

2. Description of the Related Art There have been many accidents in which a passenger on a platform accidentally falls into a space at a connection portion of a stopped train. This accident is not limited to being pushed by people on a crowded platform during a rush hour, but is also caused by a visually impaired person or a drunk person misunderstanding the connection space as an opening of a vehicle entrance door. Therefore, the applicant has
In order to prevent such a fall accident, a fall prevention device as shown in FIG. 7 has recently been proposed (JP-A-8-282492). As shown in the front view of FIG. 7C, a pair of the fall prevention devices 41a and 41b are symmetrically provided on the right and left waist plates 35 of the connection portion opening 34 of the end plate (front and rear walls) 33 of the vehicle 31. As shown in the plan view of FIG. 7A and the side view of FIG.
The pair of vehicles 41a and 41b, which are also provided on the base plate 33 of the connected vehicle 32, cooperate with each other so as to close the space of the vehicle connecting portion, thereby preventing the passenger from falling from the platform into this space.

[0003] The fall prevention device 41a of the left-hand specification is shown in FIG.
As shown in the figure, the door closer 44, in which the drive shaft 45 is urged in the normal rotation direction A by the built-in spring and whose rapid rotation is suppressed by the hydraulic oil, is fixed to the waist plate 3 by the bolt 43 via the base plate 42.
5 and a push plate 48 abutting against an opposing push plate is vertically attached to a distal end 47b of a horizontal arm 47 having a proximal end 47a fixed to the drive shaft 45. 49a is pivotally attached to the arm 47 at an interval, and one end 50a, the other end 50c, and the intermediate portion 50b of the belt 50 having a length of half or more of the distance between the vehicle connection surfaces are respectively connected to the outer edge 48a of the push plate, the base plate Of the belt support 49 and the outer edge 42a of the belt support 49. Thus, the pair of fall prevention devices 41a and 41b for each of the left and right hands of the connecting portion are indicated by the arrow A.
By the urging of the arm 47 in the direction, the opposing push plates 48 come into contact with each other as shown in FIG. 3A, and the connection space is closed by the belt 50. Even when the vehicle enters a curve and the distance between the connecting surfaces expands and contracts outside and inside the curve, the push plate 48 is always brought into contact with the belt 50 by the opening and closing movement of the arm 47 accompanying the expansion and contraction of the spring of the door closer 44. Since they are in contact with each other, the connection space is closed and passengers are prevented from falling into this space.

[0004]

However, as can be seen from FIG. 7A, the above-mentioned conventional fall prevention device has a connecting portion opening 34 (see FIG. 7C) of the opposite end plates 33, 33 of the railcar.
) Are provided on both sides of the pair of left and right hands, respectively, and are provided with the fall prevention devices 41a and 41b that contact each other by opening and closing, and thus have the following problems. That is, the wife plate 33 of the railway vehicle

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the invention of claim 1 is directed to opposing opposite sides of a vehicle connection opening to prevent a passenger from falling from a platform to a space of a vehicle connection. A leaf spring having a U-shape that is open in the direction of the side wall of the vehicle, one end of which is directly or indirectly fixed to a waistboard near a connection opening of the one vehicle; A push plate having a proximal end fixed to the other end of the spring and extending horizontally, a distal end extending vertically in the vicinity of the waist plate of the other vehicle; one end at the distal end of the push plate, and the other end of the waist plate A movable device on the one vehicle side comprising an outer hood attached to the outer edge,
A fixing frame fixed to a waist plate near a connection portion opening of the other vehicle so that a push plate of the movable device comes into contact with the pressing plate.

In the fall prevention device according to the first aspect, of two opposing wall surfaces of the connecting portion of the opposing vehicle, the wall surface of one vehicle is directly or indirectly attached to the waistboard on both sides near the opening of the connecting portion. The base end of a horizontally extending push plate is fixed to the other end of the leaf spring that opens in the side wall direction in the U-shape, and extends vertically near the waist plate of the other vehicle. An outer hood is attached between the tip of the push plate and the outer edge of the waist plate to form a movable device. A fixed frame is fixed to the wall surface of the other vehicle so that the push plate of the movable device comes into contact with the waist plate near the opening of the connecting portion. Therefore, the push plate of the movable device of one vehicle is separated from the wall surface of the one vehicle by the leaf spring and is urged in the inward opening direction toward the other vehicle. It comes into contact with the fixed frame of the other opposing vehicle and pushes it. One end of an outer hood, the other end of which is attached to the outer edge of the waistboard of one vehicle, is attached to the tip of this push plate. Therefore, the connecting portion space is completely covered at the positions on both side surfaces of the vehicle by outer hoods connected to the push plates of the movable device of one vehicle that respectively contact the fixing frames on both sides of the connecting portion opening of the other vehicle. Therefore, the passenger on the platform is prevented from falling into the connection space of the stopped vehicle. When the vehicle enters a curved road (curve), the distance between the connecting surfaces shrinks inside the curve and expands outside the curve, but the push plate inside the curve that contacts the fixed frame is subjected to the force of the U-shaped leaf spring. While the force is stored in the leaf spring by turning in the closing direction, the push plate on the outside of the curve abutting on the fixed frame further expands in the opening direction due to the urging force of the leaf spring, and the outer cover of both push plates is opened. Covers the connection space, so that falling of the passenger is similarly prevented.
Here, the fixed frame of the other vehicle is easily attached even if various devices such as rain gutters, pipes, fire extinguishers, and marker lights are installed on the wainscot compared to the movable device on the one vehicle side. In addition to the simple structure, it can be manufactured at low cost. Therefore, the fall prevention device is inexpensive and can be widely applied to existing vehicles.

According to a second aspect of the present invention, there is provided a fall prevention device provided on a pair of opposite sides of a connection portion of a vehicle in order to prevent a passenger from falling from a platform to a space of a connection portion of the vehicle. It has a biasing member that urges in the rolling direction and stores power by reversing the drive shaft, and a damper member that alleviates rapid rotation of the drive shaft, and connects the one vehicle by vertically disposing the drive shaft. Door closer means fixed to the waist plate on one side of the opening, a bearing stand fixed to the waist plate near the connection opening of the one vehicle closer to the vehicle center than the door closer means, and a base end pivotally connected to the bearing stand. A pivoting arm that is supported horizontally and pivoted in the forward and reverse directions and whose tip is located near the waistboard of the other vehicle and near the side wall of the one vehicle, respectively; A push plate vertically mounted on the The end is fixed horizontally to the drive shaft of the door closer means, is provided horizontally, and a roller pivotally attached to the tip abuts rotatably along the inner surface of the rotating arm, and rotates the rotating arm by turning in the forward direction. A drive arm to be moved, a plurality of belt supports pivotally supported at one end to the bearing base and projecting outward, one end at an outer edge of the push plate, and the other end at an outer edge of the waist plate. The movable device on the one vehicle side, the intermediate portion of which includes a belt attached to the other end of the belt support, and the connecting portion opening of the other vehicle so that the push plate of the movable device abuts. A fixed frame fixed to one side of the waist plate.

In the fall prevention device according to the second aspect, a door closer means is fixed to a waistboard on both sides of a wall surface of one of two opposing wall surfaces of a connecting portion of a railway vehicle, respectively.
Bearing stands are respectively fixed to waist plates near both sides of the opening of the connecting portion on the vehicle center side of both door closer means. The base end of the rotation arm and one end of a plurality of belt supports are pivotally supported on the bearing stand, and both of them rotate forward and backward in the horizontal direction, while the drive shaft of the door closer means has a horizontal drive shaft. The base end of the arm is fixed, and the drive arm is biased by a biasing member, for example, away from a wall surface of one vehicle and in a turning direction toward the other vehicle. Then, since the roller pivotally attached to the tip of the revolving drive arm rolls along the inner surface of the pivot arm, the push plate vertically attached to the tip of the pivot arm makes the push plate of the other opposing vehicle. Press against the fixed frame. One end of a belt having the other end attached to the outer edge of the waistboard of one vehicle is attached to the tip of the push plate. Therefore, the connecting portion space is completely covered at the positions on both side surfaces of the vehicle by the belts connected to the push plates of the movable device of one vehicle that respectively contact the fixing frames on both sides of the connecting portion opening of the other vehicle. Therefore, the passenger on the platform is prevented from falling into the connection space of the stopped vehicle.

[0010] When the vehicle enters a curved road (curve), the distance between the connecting surfaces is reduced on the inside of the curve and extended on the outside of the curve. Since the drive arm rotates in the opposite direction while turning in the opposite direction, it moves to one vehicle side while the power is stored in the biasing member, while the push plate on the outside of the curve that comes into contact with the fixed frame is provided with a rotation arm. When the urging force of the urging member turns further in the forward direction and enters the reverse curve, the former push plate follows the elongation between the connecting surfaces by the power stored in the urging member and turns in the forward direction, and the latter pushes. The plate follows the contraction between the connecting surfaces and turns in the opposite direction to store power in the biasing member. At this time, since the damper member of the door closer means reduces the rapid rotation of the drive shaft, the movement of the push plate via the drive arm and the rotation arm becomes gentle and smooth even if the distance between the connecting surfaces fluctuates rapidly. Thus, resonance and bouncing of the push plate are prevented. Further, even if a passenger leans on the belt from outside, the plurality of belt supports prevent the belt from being pushed, so that the belt is not pushed further inside. In other words, the connection space is covered without any gaps by the drive arm, the rotating arm, the belt support, the belt, etc., which smoothly respond to the change in the distance between the surfaces without requiring a special drive source such as a motor. Falling of passengers to the space is reliably prevented. Further, since the push plate is attached to the distal end of the rotating arm whose base end is pivotally supported by the bearing base fixed to the waist plate closer to the center of the vehicle than the drive shaft of the door closer, the turning radius is large, and therefore, Even outside the curve with a sharp curvature, the space surrounded by the plane and the belt including both edges of the vehicle connecting portion facing each other at a wide interval becomes narrower, so that it becomes more difficult for passengers to fall into the connecting portion space. . Here, the fixed frame of the other vehicle is easily attached even if various devices such as rain gutters, pipes, fire extinguishers, and marker lights are installed on the wainscot compared to the movable device on the one vehicle side. In addition to the simple structure, it can be manufactured at low cost. Therefore, the fall prevention device is inexpensive and can be widely applied to existing vehicles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. FIG. 1 is a perspective view showing a movable device provided in one of the vehicles 31 having a small number of devices such as pipes, fire extinguishers, and marker lights on the end plate 33 among the examples of the fall prevention device according to claim 1 of the present invention. The fixed frame provided in the other vehicle having many of the above-described devices will be described later with reference to FIG. 3, which is another embodiment. The movable device 1b is a right-handed mobile device, and a plan view and a front view thereof are shown in FIGS. 2A and 2B.
Are symmetrically mounted.

The movable device 1b is provided with bolts 9 above and below a waist plate 35 near a connection opening 34 (see FIG. 7C) of the vehicle 31.
(See FIG. 2) and a pair of brackets 3 fixed to the vehicle 3
A pair of leaf springs 4 each having a U-shape opened toward the side wall 36 and having one end 4a fixed to the bracket 3 with bolts 10, and base ends 5a and 5a connected to the other end 4b of the leaf spring 4 with bolts. A push plate 5 made of a U-shaped steel plate which is fixed at 11 and extends horizontally, and a tip 5b of which vertically extends substantially at the center between the vehicle connecting portions, and one end 6a, 6a pivotally attached to the bracket 3 is attached to the outside. An outer hood support 6 formed of a U-shaped pipe protruding toward the vehicle, and having a length substantially equal to the distance between the vehicle connecting portions, one end 7a is provided at the tip 5b of the push plate 5 and the other end 7c is provided. Is the outer edge material 8 of the waist plate 35, and the middle part 7b is the vertical other end 6 of the outer top support 6.
It consists of outer hoods 7 attached to b respectively.

The above-mentioned leaf springs 4, 4 are located at a position F in FIG. 2A where the push plate 5 at the other end 4b makes approximately 30 ° with the waist plate 35 in a free state without restriction. The push plate 5 is pressed by the wire 12 stretched between the tip 5b of the push plate 5 and the outer edge member 8 of the waist plate 35 so as to apply a biasing force to the waist plate 35.
Is compressed in advance to a position N which forms an angle of about 20 °, and at this time, the tip 5b of the push plate is separated from a fixed frame of the other vehicle on the straight road, which will be described later, by about 5 mm, while the push plate 5 By turning in the direction, it can be compressed to the maximum at the position C in FIG. Further, the wire 12 prevents the urging force of the leaf spring 4 in the opening direction of the push plate 5 from being applied to the outer top 7 and extends the life of the outer top 7. A waterproof canvas is used for the outer hood 7 so as not to injure the passenger even if his / her hand is caught, and is wrapped around the outer periphery of the vertical other end 6b of the outer hood support 6,
The outer mating edge is sewn. Note that the movable devices 1a and 1b have a shape such that the movable devices 1a and 1b always fall within the vehicle design limit regardless of the relative displacement of the opposite end plate 33 of the connecting portion as the vehicle passes through various curves on the route. , The dimensions and the mounting position do not interfere with the facilities around the route.

The other vehicle 3 is used as the left-hand fixing device 2a.
As shown in FIGS. 3 and 5, the fixed frame 13 provided on the base 2 has a waist plate near the connecting portion opening 34 (see FIG. 7C) so that the push plate 5 of the movable device of the one vehicle 31 abuts. 35,
It is fixed with four brackets 14 and a plurality of bolts 15 and has a U-shape corresponding to the shape of the push plate 5 (see FIG. 2B) when viewed from the front. Since the fixed frame 13 is attached to the waistboard 35 via the bracket 14, FIG.
As shown in the figure, even if various devices such as a rain gutter 16, a pipe 17 such as an electric pipe and an air pipe, and a cooling air duct 18 of a main motor are installed on the waist plate 35, it can be easily attached. Note that, for the left-hand movable device 1a (not shown) on the opposite side in FIG. 1, a right-hand fixed device 2b (not shown) symmetrical to the fixing device 2a is provided on the other vehicle 32.

The fall prevention device including the movable device 1b of the one vehicle 31 and the fixing device 2a of the other vehicle 32 opposed thereto operates as follows. When the vehicles 31, 32 (see FIG. 7) are on a straight road, on both sides of the connecting portion,
The left-hand and right-hand fall prevention devices are provided, respectively (see FIG. 3). Right-hand movable device 1b of one vehicle 31
As shown in FIGS. 1 and 2, the bracket 3,
A position N at which one end of the pressing plate 5 is fixed to the base plate 3 via U-shaped plate springs 4, 4 is separated from the waist plate 35 by the plate springs 4, 4, and the wire 12 is tightened toward the other vehicle 32.
The push plate 5 is opened by being biased to only a gap of about 5 mm between the tip 5a of the push plate and the fixed frame 13 (see FIG. 3) of the other vehicle. Vehicle 3
The outer hood 7 continues to the outer edge material 8 of one waistboard 35.
Accordingly, the connecting space is almost completely covered by the fixed frame 13 and the push plate 5 and the outer cover 7 which are very close to each other, so that the passenger on the platform falls into the connecting space. Is prevented.

Further, since the intermediate portion 7b of the outer top 7 is supported by the brackets 3, 3 by the rotatable outer top support 6, the push plate 5 is located at the position C, for example, inside the curve.
Even when the door is closed in the direction, the outer hood 7 is prevented from protruding, and when the passenger leans on the outer hood 7 from the outside, the outer hood support 6 supports this, so that the fall of the passenger is more reliable. Can be prevented. Also, in the event that the leaf springs 3, 3 are broken due to cracking or fatigue, the leaf spring 3 and the push plate 5 separated from the vehicle side are supported by the bracket 3 via the outer top 7 and the outer top support 6. Because it does not fall, it is excellent in safety. When the length of the outer hood 7 is short, the outer hood support 6 can be omitted. However, it has been found that the structure of the outer hood support 6 can minimize the influence of device deformation when passing a train or passing through a roller brush in a washing line due to its structure. When a vehicle enters a curved road (curve),
The distance between the connecting surfaces shrinks inside the curve and extends outside the curve. At this time, the push plate 5 on the inside of the curve turns while compressing and contracting the leaf spring 4 in the closing direction after the gap of about 5 mm is reduced and abuts on the fixed frame 13, and the force is stored in the leaf spring 4. The push plate 5 on the outside of the curve is prevented from turning by the tensioned wire 12 and the gap with the fixed frame 13 is widened.
However, the expansion of this gap is slight even in a sharp curve,
As in the case of a straight road, it is possible to prevent passengers from falling into the connection space.

As described above, in the above embodiment, the fixed frame 13 of the other vehicle 32 has the rain gutter 16, the pipe 17, and the duct 1 on the waist plate 35 as compared with the movable device 1 b of the one vehicle 31.
Even if various devices such as 8 are installed, they can be easily attached, and since the structure is simple, it can be manufactured at low cost. Therefore, this fall prevention device is inexpensive and can be widely applied to existing vehicles as compared with the conventional example described with reference to FIG. Further, in the above-described embodiment, only the U-shaped leaf spring 4 is used instead of the conventional arm 47 (see FIG. 8) for turning the push plate and the door closer 44 for turning, so that the connecting portion space is used. The number of parts is reduced, the structure is simplified, the assembling and maintenance can be simplified, and the manufacturing cost can be reduced while preventing passengers from falling down. In the fall prevention devices 1b and 2a of the present invention, since only the tip of the push plate 5 abuts on the fixed frame 13 inside the curve, there is no fear that the paint may be damaged by rubbing or contacting the vehicle wall surface. Further, in the fall prevention devices 1b and 2a, since the bracket 3 is fixed to the vicinity of the opening of the connecting portion which is separated from the side wall 36, the push plate 5 opens and closes with a large turning radius, so that the outer cover is provided even outside the sharp curve. This can cover a wider connection space, and thus has the advantage that passengers are less likely to fall into the connection space.

If the outer edge member 8 of the above embodiment is provided with a locking member for locking the front end 5b of the push plate fully closed to the position C, the fall prevention device of the first and last vehicles is obstructed. It can be put away without getting in the way, and it is advantageous during vehicle inspection. Furthermore, the bracket and the leaf spring of the present invention
One or three or more may be different from the pair of upper and lower members, and the shape of the pressing plate is not limited to the U-shape, and the leaf spring may be provided in the vicinity of the connecting portion opening of the vehicle without using the bracket. It can also be fixed directly to the hip plate. Further, the outer hood support 6 and the wire 12 can be omitted due to space or the like.

FIG. 3 is a plan view of an example of a fall prevention device according to a second embodiment of the present invention, and FIGS. 4 and 5 are lines IV-IV and V of FIG. 3, respectively.
FIG. This fall prevention device includes a movable device 21b provided on one vehicle 31 and a fixing frame 13 as a fixing device 2a provided on the other vehicle 32 opposed thereto. Since the fixed frame 13 has already been described, only the movable device 21b will be described here.
The movable device 21b urges the drive shaft 29 in the forward rotation direction indicated by the arrow A, and stores a power by the reverse rotation of the drive shaft 29 and a door closer 28 having a damper member for reducing the rapid rotation of the drive shaft 29. The bearing base 20 fixed to the waist plate 35 near the connecting portion opening 34 (see FIG. 7C) closer to the vehicle center than the door closer 28, and the base end 22a is
A pivot arm 22 pivotally supported at 0 and horizontally pivoted in the forward and reverse directions to close and open the connection surfaces, and a pusher vertically fixed to the tip 22b of the pivot arm 22. Board 19
The roller 24 is provided horizontally with the base end fixed to the drive shaft 29 of the door closer, and the roller 24 pivotally attached to the tip abuts on the inner surface 22c of the rotating arm 22 so as to freely roll, and turns in the forward direction ( (See arrow A in FIG. 7). A driving arm 23 for rotating the rotating arm 22, a belt support 25 pivotally supported at one end to the bearing base 21 and protruding outward, and one end 26 a are pushed. The other end 26c is attached to the mounting plate 27 on the outer edge of the waist plate, and the intermediate portion 26b is attached to the belt support 25.
, And belts 26 attached to the other ends, respectively.

As shown in FIG. 4, the rotating arm 22 is made of a parallel horizontal member separated by an interval between the upper and lower base plates 30, 30 ', and has a curved distal end outer surface 22b at a height similar to that of a human shoulder. Is fixed vertically. On the other hand, the belt support 25 is formed of a substantially U-shaped pipe, and its base end is rotatably pivoted with a bolt and a nut to a bearing base 20 protruding from upper and lower base plates 30, 30 '. Supported. The drive arm 23 includes a horizontal member whose base end is fixed to a drive shaft 29 protruding from the upper surface of the door closer 28, and a roller 24 rotatably pivotally attached to a distal end of the horizontal member by a bolt and a nut. As shown in FIGS. 3 and 4, the roller 24 is in contact with the inner surface 22 c of the upper rotating arm 22 so as to roll freely.

The movable device 2 of the second embodiment having the above configuration
1b is a drive shaft 2 of a door closer 28 having a biasing member and a damper member instead of the leaf spring 4 of the movable member described in FIG.
9, a roller 24 at the distal end of a drive arm 23 having a proximal end fixed thereto.
Is pressed against the inner surface 22c of the rotating arm, and the push plate 19 is turned in the direction shown by the arrow A. Therefore, the operation of the fall prevention device including the movable device 21b and the fixed frame 13 described above is basically the same as that of the first embodiment described above. The push plates 19 on both sides approach each other by the belt 26 having a predetermined length to the opposed fixed frames 13, and outside the curve, the push plate 19 and the fixed frames 13, whose movements are regulated by the belts.
While the gap between them increases, the push plate 19 inside the curve
Abuts on the fixed frame 13 and the turning arm 22 turns in the opposite direction following the contraction between the connecting surfaces while the power is stored in the urging member of the door closer 28.

In this manner, the urging member and the damper member of the door closer 28 smoothly respond to the change in the distance between the connecting surfaces without the need for a special driving source such as a motor, as in the first embodiment. As a result, the connecting portion space is covered with the belt 26 with almost no gap, and a sudden change in the distance between the connecting surfaces is alleviated, so that the resonance and the bouncing of the push plate 19 are prevented. Further, even if a passenger leans on the belt 26 from the outside, the belt support 25 prevents the belt 26 from being pushed, so that the belt is not pushed further inside. Also,
Also in this embodiment, the fixed frame 13 of the other vehicle 32 is
Compared to the movable device 1b on the one vehicle 31 side, even if various devices such as the rain gutter 16, the pipe 17, the duct 18 and the like are installed on the waist plate 35, they can be easily attached, and the structure is simple so that the cost is low. Can be manufactured. Therefore, this fall prevention device is inexpensive and can be widely applied to existing vehicles as compared with the conventional example described with reference to FIG.

The fall prevention device of the present invention may be installed at an angle to the rear plate of the vehicle to cope with different vehicle design limits for each railway company. A pair of door closer means may be installed in the upper and lower directions in order to increase the height as much as possible and to increase the pressing force. The door closer means of the present invention is not limited to the door closer of the embodiment as long as the door closer means includes an urging member and a damper member.

FIG. 6 shows various shapes which can be applied as the push plates 5 and 19 of the movable member, the rotating arm 22 and the fixed frame 13. For example, the push plate 5 or the fixed frame 13
6 (A) to 6 (E) may be an integral shape.
It may have a divided shape.
